Ineptocracy [in-ep-toc'-ra-cy] - a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers. There are three classes of people: those who see...those who see when shown...and those who do not see. - Leonardo da Vinci

I've used a couple of vlf gold detectors including the goldmaster 4b. Compared to the others, the 4b was very user friendly. It was also very effective at picking up the small gold. The meter worked well. The main advantage for the gmt was already mentioned, the auto-ground balance. The 4b isn't very difficult to ground balance but if you don't want to mess with it, then the gmt makes it easier for you.
